United States Patent Ofihce 3,123,652 Patented Mar. 3, 1964 3,123,062 BRAZER ATTACHMENT Alice Psarris, 25 Groton St., Lowell, Mass. Filed Apr. 25, 1962, Ser. No. 190,048 Claims. (Q1. 12625) This invention generally relates to braziers and has for its primary object to provide, in a manner as hereinafter set forth, novel means in the form of an attachment for concentrating heat from the usual charcoal on the gridsupported utensil or food, thus accelerating the operation in addition to economizing in fuel.

Another important object of the present invention 1s to provide a heat concentrating attachment of the character described which is adapted to be readily suspended from any desired portion of a conventional grid above and spaced from the burning charcoal or other fuel in the fire bowl.

Another object of the invention is to provide an attachment of the aforementioned character which is readily adjustable for utensils of various sizes and to meet other conditions.

Still another important object of the invention is to provide a brazier attachment of the character set forth which is adapted to function as a fire box for supporting the burning charcoal close to the utensil or food on the id. Another object of the invention is to provide a heat concentrating guide, funnel or the like for braziers which comprises a single sheet of aluminum or other suitable bendable metal.

Other objects of the invention are to provide a brazier attachment of the character described which is comparatively simple in construction, strong, durable, compact, of light weight and which may be manufactured at low cost.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings tforming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 1 is a perspective view, showing an attachment embodying the present invention in position for use, a portion of the fire pot and grid being broken away;

FIGURE 2 is a vertical sectional view on an enlarged scale, taken substantially on the line 2-2 of FIGURE 1;

FIGURE 3 is a vertical sectional view substantially similar .to FIGURE 2 but showing the device in use as a fire box;

FIGURE 4 is a fragmentary view in horizontal section on an enlarged scale, taken substantially on the line 44 of FIGURE 1;

FIGURE 5 is a plan view of the blank;

FIGURE 6 is a vertical sectional view substantially similar to FIGURE 2 but showing the device in use in a brazier comprising a relatively low grid; and

FIGURE 7 is a vertical sectional view substantially similar to FIGURE 3 but showing the manner in which the bendable fingers may be interlocked when the device is used as a fire box.

Referring now to the drawing in detail, it will be seen that reference numeral 8 designates generally the blank from which the device is formed. The blank 8, which may be of aluminum or any other suitable metal, comprises a generally segmental or fan-shaped sheet 9 of suitable dimensions and of substantially the shape shown to advantage in FIGURE 5 of the drawing. The sheet 9 is rolled to provide a generally frusto-conical tube or inverted funnel 16. The tube or funnel 10 is open at its upper and lower ends.

The sheet 9 has formed in one end portion a plurality of spaced pairs of slots 11 which parallel the end 12 of said sheet. Formed integrally with the other end 13 of the sheet 9 is a pair of bendable tongues 1-4. The tongues 14 are engageable selectively in the pairs of slots 11 to secure the device in its tubular form with the end portions of the sheet 9 lapped.

Formed integrally with the upper or top edge 15 of the sheet 9 is a pair of bendable tongues or hooks 16 which are adapted to be bent over selected wires or rods 17 of a conventional grid 18 for suspending the device from said grid. The grid 18 is mounted on the fire bowl 19 of a brazier or charcoal grill 2%, said fire bowl being provided with supporting legs 21.

Extending into the sheet 9 from the lower or bottom edge thereof is a series of slits 22 providing bendable fingers 23. The fingers 23 may remain as shown in FIG- URES 1 and 2 of the drawing. Or, the fingers 23 may be bent as illustrated in FIGURES 3, 6 and 7 of the drawing.

It is thought that the use or operatic-n of the device will be readily apparent from a consideration of the foregoing. Briefly, the sheet 9 is rolled to tubular form of the desired diameter or size, as indicated at It and secured by inserting and clinching the tongues 14 in the appropriate slots '11 in the manner shown in FIGURE 4 of the drawing. The small or upper end of the .device is then engaged with the underside of the grid 18 and firmly secured by bending the tongues .16 over the adjacent rods or wires 17 of said grid. Thus, the device may be located as desired beneath the grid. The inclined or lower end of the device facilitate mounting same adjacent the periphery of the grid I8 when the bottom of the fire bowl 19 is rounded. Of course, the coffee pot or other utensil is placed on the grid 18 over the upper end of the tube or inverted funnel It In FIGURE 2 of the drawing, reference numeral 24 designates a relatively small pile of charcoal which has been concentrated beneath the tube 10. Heat from the fuel 24 is guided to and concentrated on the utensil by the tube Iiiin an obvious manner.

If desired, the device may be used as a fire pot or box by placing the charcoal 24 therein. This is shown in FIGURE 3 of the drawing. When the device is to be so used, any or all of the fingers 23 may be bent inwardly and upwardly to provide a bottom for supporting the charcoal in the tube It said bottom having draft slots or openings therein. In the embodiment of FIGURE 7 of the drawing, the fingers 23 are of suificient length to permit the free end portions of as many of said fingers as may be desired to be bent into interlocking hooks 25.

In FIGURE 6 of the drawing, reference numeral 26 designates generally a brazier comprising a fire bowl 27 having mounted thereon a relatively low grid 28. To facilitate use of the device on braziers of this type, the tube 10 may be shortened by bending the fingers 23 outwardly and upwardly as shown.

It will be observed that the complete device comprises a single sheet or piece of suitable metal. Also, the sheet 9 may be rolled in either direction to the tubular form of the device. Still further, the device may be readily removed and flattened out, if so desired. In FIGURE 1 of the drawing, the reference numeral 29 designates the usual center post in the fire bowl 19 which supports the grid 18. In addition to providing the bendable fingers at 23, the slits 22 allow the entrance of air into the tube 10 adjacent the charcoal :24 for promoting combustion.

The device may, of course, be made in various sizes for different uses. Also, if desired, the slits 11 and tongues 14 may be so orientated as to provide a substantial-ly cylindrical tube when the sheet 9 is rolled and the lapped end portions thereof are secured.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

1. A heat concentrator comprising a one-piece unitary tube formed of rolled sheet material open .at its ends, and means formed from part of said tube for suspending said tube from a grid of a fire-bowl and spaced from a bottom Wall thereof, said tube including fingers on its lower end portion formed by longitudinally slitting said sheet material and bendable inwardly and upwardly for supporting fuel in said tube.

2. A heat concentrator in accordance with claim 1, said means including fingers formed integral with and disposed on the upper end of the tube bendable over the grid.

3. A heat concentrator in accordance with claim 1, said fingers including interlocking hooks on their free ends.

4. A heat concentrator in accordance with claim 1, said tube being generally fnusto-conical, longitudinally split and circumferentially adjustable.

5. A heat concentrator comprising a 0ne-piece unitary tube formed of rolled sheet material open at its ends, and means formed from part of said tube for suspending said tube from a grid of a fire bowl and spaced from a bottom wall thereof, said tube including fingers on its lower end portion formed by longitudinally slitting said sheet material and bendable upwardly and outwardly for shortening the length of the concentrator wherein the over-all length of the concentrator may be greater than the distance between a grid and a bottom wall of a fire bowl.
